The legendary mythos of the caped crusader has marched for over seventy-five years since Batman’s first appearance inDetective Comics #27in 1939. Created by Bob Kane and Bill Finger, Batman has risen into one of the most popular superheroes of all time and one of the pillars of the DC universe. Over the years, Batman has defined what a dark hero should be, and his story has expanded along with his laundry list of villains in his rogues' gallery.

The world’s greatest detective has even debuted outside the world of comics, featuring in multiple live-action appearances and entire trilogies. However, in the long list of characters that share Batman’s universe, there are many who have never appeared on screen alongside him. Here are some majorBatmancharacters that have never appeared in a live-action movie.

8Aaron Cash

One-Handed Defender Of Arkham Asylum

Aaron Cash is not a major character in terms of ability, but instead, his presence holds a fair amount of weight in Gotham City. Cash first appeared in theArkham Asylum: Living Hellmini-series, where he debuted as an Arkham security guard in charge of the most psychotic criminals in Gotham.

Cash made another appearance in theBatman: Arkham Asylumvideo game, where his character played a reasonable role. While Arkham Asylum has not been fully explored, there is hope that the next generation ofBatmanmovies will dive deeper into the city’s madness and that Cash will appear to aid Batman in containing the terror.

5Jeremiah Arkham

The Keeper Of Gotham’s Insanity

Jeremiah Arkham is paramount in Gotham City’s history and one of the backbones that keeps Arkham Asylum running. First appearing inDetective Comics #593, Jeremiah is the astute and almost cryptid-like head of the asylum who has been infected by his patients' madness.

In countless encounters, Jeremiah tries to take over the city, put an end to Batman, and even serve as the Black Mask for a short time. The complexity of Jeremiah Arkham’s character would make a great villain for an upcomingBatmanmovie, taking the story deeper into the madhouse of Arkham Asylum.

4Ace

The Batman’s Best Friend

There are not many that Batman trusts with his life outside of the immediate members of the family. However, the four-legged bat-hound is a cherished member of the bat family and has proven more than once that he is as dependable as Alfred himself.

Ace first appeared inBatman #92and made countless appearances in other media, such asBatman BeyondandDC League of Superpets. Unfortunately, the companionship between Batman and Ace has not yet received the live-action adaptation they both deserve. Hopefully in some shape or form, Ace gets his time in the spotlight in James Gunn’s budding DC films.

The Son Of The Batman

Damian Wayne is one of the newest members of the bat family, being the direct descendant of Bruce Wayne through progeny with Talia Al’Ghul. Damian arrived on the scene as a surprise to everyone, even the fans, in his first appearance inBatman: Son of the Demon.

As an arrogant but deadly individual, Damian took the mantle of Robin as his birthright. Since then, Damian has worked hard to break the grooming of the League of Shadows and learn his father’s idealistic ways. Damian has become a perfect piece to the Batman puzzle and would be a great addition to upcoming live-action installments.

Batman Under The Red Hood

1Red Hood

The Fallen Hero Turned Anti-hero

Jason Todd is perhaps the most polarizing name when speaking about the mythos of Batman. Starting out as the replacement of Dick Grayson after a damaging emotional split between the two, Jason Todd arose as the new Robin and took to it with a bright future ahead of him.

Unfortunately, a series of decisions led the young man to his death at the hands of the Joker and signaled one of the darkest times in Batman’s history. Jason Todd would reemerge as theRed Hood, the lost partner of Batman, returned from the dead. Jason Todd holds a tremendous amount of weight in the entire DC universe, and it would be spectacular for Under the Hood to be adapted into a live-action film.
